The point of Walter's argument was not about performance but, 
safety guarantees. Guarantees which cannot be given by C, or by 
Rust due to it's marking as unsafe (as I understand it). So the 
extra info is very useful for the programmer.

Also, I would compare apples to apples here and compile both the 
C program and the D code with LLVM.
